| After the starter has been on 12 volts for a while it may have worn it down to the point where only 12 volts will crank it,or it may have a 12 volt selonoid on the 6 volt starter. |

Other question Guys:
1) Could my problem be caused by a too much used bushing ?
2) Is there Any danger / problem if I try to start it with my 6 volts battery while it is desassembled from the core transmission ? |
1. Are you talking about the bushing that fits into the transmission bell housing that supports the starter shaft? That should not be a problem, but just put a small amount of grease on the starter shaft when it goes back in and it will be fine.
2. Running the starter while out of the transmission will not harm it.
I agree with Jake74, that your starter could be worn excessively by the 12V operation, and may need to be rebuilt. A faulty solenoid could be the problem, as it may have worn electrical contacts inside which prevent enough current from reaching the starter motor. Or, it might have damage to the armature from handling the 12V current. |

But you may have a difficult time trying to test it if you don't have a way of supporting the shaft. If it's not bolted to the transmission, the armature is not supported and it can't spin freely.

U could use a hard start solenoid in conjuntion and that may be the ticket.... 
It's probably after being used on 12v for so long it needs the extra jolt to get it going .....
This fix has worked for me in the past...Might be worth a shot
Or just get that unit re-built and it should be fine....
Hope it helps  |

Hi Guys,
I wanted to give an update on my story,
I think I am not lucky, 
I just bought another 6v starter on ebay said as restored, the time to restore mine later this winter, but when I installed my new purchase nothing happened, just the solenoid worked.
After few minutes installed I noticed that the starter was very hot, the same as my 6v battery, then I tried to unplug the battery which made big sparks.
After I checked with an ohmmeter, I noticed an impedace between + and body of the starter and saw as well after I remove starter that the rotor was always engaged even with no power on it ...
I have contacted the seller who is a professional shop, I hope they will give my money back or send me another one, lets see, but at the moment I am still stuck with my problem.
My next option is to check a local shop who can restored my OG starter.

Hi Guys,
I would need some help.
The 56 cabrio I just bought was converted in 12volts during the past few years.
Now the original engine is back in place and I want to put it back in 6 volts.
The starter that is in place is the original one (6 volts) and was used in 12 volts without any problem.
When I put a 6 volts battery (battery is new) the starter engages onto the flywheel but stops just after that.
When I put a 12 volts battery it works well.
If someone has any idea of what could be my problem ??
Thanks in advance for your help.

How could this happen? According to many Samba posters, operating a 6 volt starter at double the design voltage and double the design current will be just fine. If you want to make sure you get a rebuilt starter, take it apart and make sure the armature commutator has been machined parallel to the brushes and it has new brushes. It should also have a new bushing installed, use calipers for measurement. Ask the seller if the armature was tested on a growler for winding-to-winding shorts, winding shorts to ground and open windings. The solenoid current should not be over 22 amps after the solenoid engages and 44 amps before it engages and the total no load current should not be over 110 amps. Make sure it rotates in the correct direction; field coils for other starters will fit, but they cause the starter to rotate in the opposite direction, which append to a friend. Make sure the solenoid is good with new contacts. Make sure whole starter is painted to prevent rust. This is how I test the starters I rebuild.
Most rebuilds don’t have the armature support adapter to perform the above quality control tests. However, most stores will sell an endless supply of untested starters so can install them one by one. Some shops sandblast and paint old untested starters then sell them as rebuilt.

If the bushing is worn out it can cause starting problems and damage the innards of the starter. BTDT.
As for testing without the bushing it might work, or not, so not good for testing purposes. Plus again it can damage the innards.
